Fix recursive loading in tubes, logging when loading tubes in viewer

[sneakers-the-rat]

formerly the recursive tube loading wouldn't forward the recursive parameter on, so it wasn't actually recursive, it was just 2 layers. oopsies.

Also added more logging in the viewer for when loading tubes fails - this happens often because people are working on the tubes while it's running, so they are sometimes in invalid states, and currently there is no feedback for that which sucks.

Footnotes

1. 8 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on main (d1d3c7c) during the generation of this report, so c7be157 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
